[SOLVED] DELL Inspiron 15R 3521/5521 BIOS Unlock

[Kevanness]

Hello! I would like to request unlock the Advanced Menu in bios InsydeH2O  A16
Model: Dell Inspiron 15R 5521-5461 i73537U 6GB AMD 8730M (though BIOS states 3521 model!)
BIOS Type: Insyde H20
BIOS Version: A16

My problem is dedicated GPU (laptop hangs on driver install , safemode disable device - works ok though fan keeps loud). Can dedicated GPU be disabled through menu?

Trying to fix a bricked Dell 3521... Does anyone have the .hdr and .rom files? I'm not sure how to extract them from the bios. Thanks

So I have a Dell Inspiron 3521 with the A12 version of the InsydeH20 Bios, I downsloaded this file and despite being named "generalized" there's a read me file in which it says the mod is only for "this pc", I assume it was modified accordingly to the info detailed in the bios dump of that user, can anyone modify it for me or tell me what do I need to do in order to make it work with my pc?

UPDATE
Hi. I tried to use eGPU on my laptop for second desktop monitor purposes but to no avail. It doesn't get detected on Device Manager. I guess unlocking the BIOS might help.

Specs
* Windows 10 Pro 20H2
* 12GB DDR3 RAM (4GB Hynix + 8GB Kingston)
* 128GB SSD w/ 500GB HDD for data
* Intel Core i5 3rd Gen 3337U
* Intel HD Graphics 4000 w/ AMD Radeon HD 8730M as discrete GPU
* Nvidia/Sapphire GeForce 8800GT eGPU (Windows didn't detect it)
* Realtek NIC & HD Audio
* A12 Dell BIOS (Downgraded from A16)

I have dumped my A12 BIOS using NEW_BACKUP_FPTs program

I don't want my eGPU investment to be such a waste & I'm willing to donate some money to those who helped me getting my eGPU recognised.

This is my first time modding my BIOS so detailed instructions is needed. Thank you.
